Description

TECHNICAL FIELD

[0001] The application belongs to the field of submarine ice-breaking and surfacing in polar regions, and particularly relates to a submarine ice-breaking and surfacing auxiliary device based on electromagnetic resonance and an ice-breaking method thereof. BACKGROUND

[0002] In recent years, with the continuous innovation and development of science and technology, the problem of resource shortage cannot be ignored. In such an era of scarce energy and natural resources, it is urgent to find a "paradise" rich in resources for exploitation. In today's international environment, the polar region is rich in natural resources and has a unique ecological environment, which has attracted worldwide attention. However, the polar region has extremely low temperature and extremely high wind speed, which brings great difficulties to exploration and exploitation. At the same time, global climate change has a significant impact on the polar region, leading to accelerated ice cap melting, rising sea level, and changes in the ecological system. These changes not only affect biodiversity but also pose new challenges to the feasibility assessment of resource development. Therefore, how to correctly detect and evaluate the environment of the polar region has become the top priority for polar resource exploitation. Polar submarines play an important role in this regard. First, polar submarines can perform tasks in ice-covered waters, giving them a unique advantage in polar exploration. Second, the special design and functions of polar submarines make them perform well in extreme environments. They usually have reinforced hulls and power systems that can break through thick ice layers and surface. This ability is crucial in polar exploration. However, because the polar region is covered with ice and snow all year round, how to safely and efficiently break through the ice has become a key factor for submarines to successfully complete their tasks. Therefore, research on submarine ice-breaking and surfacing is particularly important. In general, the most commonly used method for submarine ice-breaking and surfacing is direct extrusion of the submarine and the use of missiles to break the ice. For example, a polar unmanned underwater ice-breaking system with the application number CN202011349921.0 uses high-energy explosives to break the ice before surfacing. This method requires a large amount of resources and energy, and the structure of the submarine is also damaged. SUMMARY

It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict, and the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0034] DETAILED DESCRIPTION 1: see Figures 1-8 In this embodiment, a submarine floating auxiliary icebreaking device based on electromagnetic resonance includes a mounting platform 1, a resonance system, and a hook 6. The mounting platform 1 is arranged on the submarine's hull. The top of the resonance system is connected to the hook 6. The resonance system is installed in the mounting platform 1.

[0035] In this embodiment, the mounting platform 1 is a double-layered outer shell in the shape of a circular truncated cone without a top cover. The sandwiched part is provided with a plurality of small holes to help the wire pass from the submarine to the surface of the magnetic piece at the upper end. The resonance system includes a magnetic end 2, a spring 3, and a magnetic piece 4. The spring 3 is installed between the magnetic end 2 and the magnetic piece 4. The magnetic end 2 and the magnetic piece 4 are installed at the lower end and the upper end of the mounting platform 1, respectively. The magnetic piece 4 is connected to the hook 6.

[0036] In this embodiment, the magnetic piece 4 is wound with a wire 5. The end of the wire 5 is installed in the submarine's hull.

[0037] In this embodiment, when not powered, the magnetic end 2 and the magnetic piece 4 are attracted to each other. When powered, the magnetic end 2 and the magnetic piece 4 repel each other. The magnetic end 2 is inlaid in the base of the mounting platform 1. The other end connected to the spring 3 above is the magnetic piece 4. In the unpowered state, the magnetic end and the magnetic piece are in a state of mutual attraction. In the powered state, the magnetic pole of the magnetic piece changes with the change of the current direction.

[0038] In this embodiment, each claw of the hook 6 is connected to a motor 7. The magnetic piece 4 is connected to each claw of the hook 6, and a hole 8 is formed at the connection. The hole 8 is used to pass the wire connected to the motor 7.

[0039] The installation platform 1 is a slightly larger circular platform than the magnet, which is provided with a groove to inlay the magnetic part 4 therein, so as to fix the resonance system on the submarine shell, the resonance system is inlaid in the installation platform 1, the top hook 6 repeatedly vibrates up and down through the continuous attraction and repulsion force between the spring 3 and the magnetic part 4 and the magnetic end 2 after alternating current is passed through, the hook 6 at the top of the resonance system is responsible for inlaying into the ice block tightly before the resonance system starts, through the elastic tension of the spring 3 and the mutual repulsion force of the two magnets at the moment of power-on and the upward impact force of the submarine, then the hook naturally contracts, so that the ice block follows the hook and vibrates continuously through the resonance system, according to the relevant research, for the ice block with a size of 60m*30m, when its thickness is 0.5m-2.5m, its natural frequency is 0.6Hz-11.4Hz, and the average thickness of the polar ice is 2-4m, therefore, the forced vibration frequency of the ice can be controlled within the relevant range, finally, due to the forced vibration frequency close to the natural vibration frequency, when the frequency of the external excitation is close to the natural frequency of the ice block, the system will vibrate with a larger amplitude, so as to accumulate energy, the process of energy accumulation is not energy release, but energy storage, when the accumulated energy exceeds the limit of the system, the system will be damaged, at this time, the energy is released, so as to achieve the effect of resonance energy accumulation, so that the submarine can produce the maximum damage effect with smaller energy, and the submarine ice-breaking operation is completed.

[0040] DETAILED DESCRIPTION 2: see Figures 1-8 The ice-breaking method of the submarine floating auxiliary ice-breaking device based on electromagnetic resonance is described, which comprises the following steps:

[0042] Step 2: when the submarine reaches the estimated position, leave a distance for floating;

[0043] Step 3: then the submarine floats up, and at the same time, the magnetic part 4 is rapidly powered on, at this time, the magnetic part 4 and the magnetic end 2 repel each other, under the joint action of the elastic force of the spring 3, the magnetic force and the upward impact force provided by the submarine, the hook 6 is rapidly launched upward and into the ice layer;

[0044] Step 4: the tip of the hook 6 is contracted under the control of the motor 7, and the ice layer is grabbed;

[0045] Step 5: constantly changing the energized state of the magnetic piece 4, so that the polarity is constantly changing, combined with the elastic force of the spring 3, the hook 6 in a certain range of amplitude position up and down vibration, in turn, drive ice layer resonance, through the vibration eventually cause ice layer broken, let the ice block by the forced vibration frequency and the inherent frequency of ice block close, form resonance energy gathering effect, so that the submarine can gather energy around the hook 6 gradually with smaller energy consumption, when the energy gathering exceeds the limit, will release all the energy, eventually cause ice layer broken, can assist the submarine to complete the ice breaking work.

[0046] When breaking ice, first adjust the distance and angle between the hook 6 and the ice layer under the control of the motor 7, at this time the magnetic piece 4 is not energized, and the magnetic end 2 is attracted to the opposite sex, the magnetic force and the weight and the elastic force of the spring 3 keep balance, when the submarine reaches the estimated position, there is a certain distance of the submarine, the submarine rises while the magnetic piece 4 is quickly energized, at this time the magnetic end 2 and the magnetic piece 4 are the same kind of repulsion, under the action of the elastic force of the spring 3 and the magnetic force and the submarine's own up floating force, the hook 6 is quickly launched upward and shot into the ice layer, then the hook 6 tip is contracted under the control of the motor 7, and tightly holds the ice layer, at this time the submarine stops the up floating process and maintains a certain distance with the ice layer, constantly changing the energized state of the magnetic piece 4, so that the polarity of the magnetic end 4 is constantly changing, combined with the elastic force of the spring 3, so that the hook 6 in a certain range of amplitude position up and down vibration, drive ice layer resonance, let the ice block by the forced vibration frequency and the inherent frequency of ice block close, form resonance energy gathering effect, so that the submarine can gather energy around the hook 6 gradually with smaller energy consumption, when the energy gathering exceeds the limit, will release all the energy, eventually cause ice layer broken, can assist the submarine to complete the ice breaking work.
